Abstract
This article integrates the literature on interorganizational relationships into six generalizable determinants of relationship formation, applies these determinants to the prediction of six types of interorganizational relations, and proposes hypotheses for future research that specify the conditions under which each determinant will he more likely to predict different types of relations. These determinants provide the basis for a general theory of interorganizational relationships and suggest that alternative theoretical perspectives on relationship formation provide important but only partial insights into why organizations enter into relationships with one another.
